ID 1.14.11.30 DE hypoxia-inducible factor-asparagine dioxygenase. AN HIF hydroxylase. CA 2-oxoglutarate + L-asparaginyl-[hypoxia-inducible factor alpha subunit] + CA O2 = (3S)-3-hydroxy-L-asparaginyl-[hypoxia-inducible factor alpha CA subunit] + CO2 + succinate. CC -!- Contains iron, and requires ascorbate. CC -!- Catalyzes hydroxylation of an asparagine in the C-terminal CC transcriptional activation domain of HIF-alpha, the alpha subunit of CC the transcriptional regulator HIF (hypoxia-inducible factor), which CC reduces its interaction with the transcriptional coactivator protein CC p300. CC -!- The requirement of oxygen for the hydroxylation reaction enables CC animals to respond to hypoxia. DR P59723, HIF1N_DANRE; Q9NWT6, HIF1N_HUMAN; Q8BLR9, HIF1N_MOUSE; //
